The primary risk for CT technologists related to radiation exposure is an increased lifetime risk of developing cancer, primarily leukemia and thyroid cancer, due to chronic, low-dose radiation exposure from repeated occupational duties. While modern CT technology incorporates significant safety features to minimize radiation dose, technologists can still be exposed to scatter radiation from the patient during scanning.
Even with the advancements in dose reduction techniques, the potential for exposure exists because CT scanning involves ionizing radiation, which can damage cellular DNA. This damage, if unrepaired or improperly repaired, can lead to mutations that contribute to cancer development over time. The risk is cumulative, meaning that the longer a technologist works in CT and the more exposures they encounter, the higher the theoretical risk becomes. Strict adherence to ALARA (As Low As Reasonably Achievable) principles is crucial for mitigating this risk. To minimize exposure, CT technologists must consistently employ radiation safety practices. These include always wearing personal protective equipment such as lead aprons and thyroid shields, maintaining a safe distance from the patient during scans (utilizing the control booth), using collimation to limit the X-ray beam to the area of interest, and being mindful of scan parameters to optimize image quality while minimizing dose. Regular monitoring of personal radiation exposure levels through the use of dosimeters is also mandatory to track cumulative dose and identify any potential issues.What are the different types of CT scans a CT tech might perform?
A CT technologist performs a wide range of CT scans, tailored to different body regions and clinical indications. These scans can be broadly categorized by the anatomical area being imaged, the specific contrast agents used (if any), and the clinical questions the scan aims to answer. Some of the most common types include head CTs, chest CTs, abdominal/pelvis CTs, and CT angiography (CTA).
Head CT scans are frequently ordered to evaluate trauma, stroke, headaches, or other neurological symptoms. They can identify fractures, hemorrhages, tumors, and other abnormalities within the brain and skull. Chest CTs are used to diagnose lung diseases such as pneumonia, pulmonary embolism, and lung cancer, as well as to evaluate the mediastinum and heart. Abdominal and pelvic CTs are invaluable for assessing conditions affecting the liver, kidneys, spleen, pancreas, bowel, and reproductive organs, including tumors, infections, and inflammatory processes.
CT Angiography (CTA) is a specialized CT scan that visualizes blood vessels. It requires the injection of intravenous contrast and is performed to assess for aneurysms, stenosis (narrowing), blockages, and other vascular abnormalities in various parts of the body, such as the brain (CTA Head), aorta (CTA Chest/Abdomen), and extremities (CTA Runoff). Beyond these core areas, CT techs might also perform specialized scans like CT enterography (for small bowel imaging), cardiac CT (for coronary artery assessment), and CT guided biopsies.
